Quaternary structures of proteins include different protein and non protein moiety to work together.

Option B

<h3>Explanation:</h3>

Proteins are the polymer of amino acids which are formed after several processing. The polypeptide chains are formed when the transcripted mRNAs are translated in the Ribosomes to produce the polypeptide chains. Then they are further processed by slicings and adding and cutting of several protein parts to this main polypeptide chains and they are slightly folded by means of hydrogen bonds between the polypeptide chain atoms to give a slightly coiled structure. Now this secondary polypeptide undergoes several structural modifications by chaperon proteins which introduce different ionic, disulphide, covalent etc bondings between different parts of polypeptide chain to produce a highly coiled tertiary structure.

Now in some proteins like haemoglobin, there are the protein part i.e globin associated with haem chains, which is the Quaternary structure of proteins. It's formed when different proteins are together associated to perform a particular function.

It is true that epidural bleeding is a. associated with widespread vascular disruption. b. characterized by a lucid interval imm

oksian1 [2.3K]

Answer:

b. characterized by a lucid interval immediately after injury.

Explanation:

Epidural bleeding is the accumulation of blood between the dura (membrane lining the brain) and the skull. This bruise is typically caused by an acute head trauma that ruptures the middle meningeal artery. This bleeding is characterized by a lucid interval immediately after an injury to this region.

This bleeding has its most frequent location at the temporal lobe level, between the bone and the dura mater. It is due to rupture of the middle meningeal artery, usually by a temporal bone fracture. The artery runs on the outer surface of the dura, housed in a groove in the inner bone board. The fracture may clamp or cut the artery, leading to a bruise.

jek_recluse [69]

Answer:

Option (3)

The arms mostly contains old blue and blue-white stars

Explanation:

Spiral arms are the regions in stars extending from the middle of spiral galaxies and the barred spiral. Those long, thin areas look like a spiral and therefore give their name to spiral galaxies.

Spiral arms, though, include many young, blue stars, that render their arms so bright (due to the high mass density and the fast stellar forming rates).

In the carbon cycle, decomposers return carbon to the soil. Which of the following is NOT something that decomposers can break d

erastova [34]

Answer:

b. the bodies of dead plants and animals.

Explanation:

decomposers break down the dead organisms and return the carbon in their bodies to the atmosphere as carbon dioxide by respiration. in some conditions, decomposition is blocked. the plant and animal material may then be available as fossil fuel in the future for combustion.
